Figure 37. The HVD230’s Input, CAN Bus, and X250’s RXD Output Waveforms
Figure 37 displays the HVD230’s input signal, the CAN bus, and the competitor X250’s receiver output
waveforms. The input waveform from the Tektronix HFS-9003 Pattern Generator in Figure 36 to the HVD230
is a 250-kbps pulse for this test. The circuit is monitored with Tektronix P6243, 1-GHz single-ended probes in
order to display the CAN dominant and recessive bus states.
Figure 37 displays the 250-kbps pulse input waveform to the HVD230 on channel 1. Channels 2 and 3 display
CANH and CANL respectively, with their recessive bus states overlaying each other to clearly display the
dominant and recessive CAN bus states. Channel 4 is the receiver output waveform of the competitor X250.
